Abstract
A sensitive and quantitative analytical method for determining element al sulfur in a biological system was developed. Elemental sulfur was d etermined after extraction with petroleum ether by cyanolysis and ferr ic thiocyanate color formation in acetone. The method was successfully applied to show that sulfide was oxidized by Thiobacillus thiooxidans to elemental sulfur nearly stoichiometrically when further oxidation of elemental sulfur was inhibited by N-ethylmaleimide.
